' In. the drawing similar reference charactersv refer to Isimilar parts throughout the several views, and the sectional views are ltaken lookingl in the direction of thelittle arrows at the ends of the section lines.

Referring to the drawing, 1 is the base which also constitutes the coin receptacle.

` 2 is the supporting ring for the glass merchandise cylindrical case resting upon the base.l is the cylindrical merchandise vThe merchandise is in the form of balls of gum. 4 is the dome for the case.

5 is the gasket interposed between these parts to permit of their nbeing tightly clamped together. 6 is the central upright assembly connecting rod which holds the parts in assembled relation. It has a right hand screw thread 61 at each end.A The rod 6 is reduced and extended at 62 at each end in a small pin. Y

The base 1 is provided with an upwardly extending hollow boss 1 which is suitably perforated for theV said assembly rod 6 and the dome 4 has a similar downwardly-extending boss 41 to receive the upper end of said vassembly rod. Towardthe upper end of the rod is a hexagonal nut 8 securely pinned to the rod 6 and tt-ing into a receptacle 42 in the under side of said boss 41 to retain the said rod against turning. An elongated tubular nut 7 is properly screw threaded at top and bottom to said rod 6 and clamps the base and dome against the merchandise cylinder 3. The outer end of each nut contains a left-hand thread.

A key 9 is provided with a central bore 91 to accommodate the pin 62 at the end of the rod. It is externally threaded with alefthand thread 92 corresponding to the lefthand thread at the outer end of each said nut. The screw 92 of the key is slightly tapered and the same is screwed firmly yinto the nut. The key is then used for inserting the nut and when the nut seats, owing to the fact that the key has a left-hand thread it will be withdrawn, leaving the nut securely in place. This avoids any likelihood of its being tampered with and makes a very satisfactory lock for this kind of machine.

rlhe machine is secured to a post or wall by suitable bolts through the perforations 1 in the base.

Having thus described these parts in their general relation, they will now be described in detail.

10 is the bottom pan of the entire delivery structure and has formed therein the bottom part of the merchandise delivery chute 101. terminating in the delivery spout- 11 for the delivery of the ball of gum, the merchandise. A notch is formed in the. pan 10 for the downward passage of the coin into the. coin receptacle in the base. Around this is disposed a wall 102 having upwardly projecting lugs 103 cooperating with the projections on the underside of the merchandise slide casing 14 to prevent the unauthorized extracting of coin by inverting and manipulating the machine.

A delivery opening is formed in the side of the case at 11 for the spout 11.

12 is the coin controlled merchandise delivery slide which is provided with a projecting handle 121 for manipulation. It is perforated at 122 for the passage lof a ball of gum, the merchandise, and delivery of the same to the delivery chute, a rib 122 beingk formed around the aperture 122 on the under side of the slide, as indicated in Fig. 6. The slide 12 is notched at 123 for the reception of coin. A depression 124 is formed in the rear side of this notch 123 to permit the passage of the slide under the coin controlled dog when the dog` is. raised by the introduction of a coin. 125 are lugs on the upper surface of the slide to agitate the contents of the receptacle and insure the delivery of one of the balls of gum. 126 is a segmental gate made, integral-with the slide 12 and depending therefrom, and it controls the aperture. to the spout for the delivery of the balls of gum. VIt is initially in the open position as seen in Figs. 3' and 4 and is disposedto close the passage as seen in Figsy and 6, when a ball is being dropped into the chute, the detail ofthe closed position being more clearly shownin Fig. 6. 127 is the downwardly depending lug on the slide for engagement by the. main spring 17 which is coiledaboutand disposed on the central connectingl rod 6 with its opposed end reacting on lug 146 on the under side of the slide casing 14, hereafter to be described. v.

128 are segmental annular ribs on the under side of the slide 12 cooperating with groove 147 on casing 14 hereafter to be described.

The slide casing 14 is provided with a downwardly projecting curved wall 141 forming a part of the merchandise chute and this cooperates with. the aperture 122 in the slide to insure the delivery of a singlel ball at a time into the chute. This slide is provided With a coin chute 142 for theintroduction of the coin beneath the coin controlled dog. It is provided with av journal hub 143 for carrying the slide. A spring 144 is disposed to the outside or periphery of the path of the slide and is held in position by an eye at the end over the upwardly projecting vpin 145 on the case V14. The detail in Figs. 4 and 5 show the relation of the parts as they clearly appear, the coin, a cent, being shown in dotted lines in Fig. 4.

The inwardly projectiirg toothed lugs 145 are provided on the case and cooperate with the reversible pawl 13 pi voted on the under side of the slide 12 and held yieldingly in central position by the compressed coiled spring 131, secured to the under side 'f of the said slide 12. The relation and cooperation of these partel clearly appearing in Figs. 5 and 16.

146 is the downwardly depending lug on the under side of slide casing 14 for engagement with the actuating spring 17 already identiiied. rlhercasing 14 is grooved with an annular segment groove at 147 beneath the coin slide which cooperates with ribs 128 underneath the slide thereby insuring the advancing of a coin Without possibility of stopping and permitting free act-ion of the coin controlled dog with the' slide in position until a proper coin has been introduced.

v is the slide case cover and is provided withv a segmental dog lhousing 151 within which is pivotedthe coin controlled dog 16 on screw pivot 161. Thisdog is held :down to its Work by the dog spring V162,A one end of which engages over the top ot the .dog and the other endk of Which extends through a perforation'on the endwall of the dog housing against which it reacts as clearly appear-s in F ig. 13. The dogv normally drops into engagement with the slide Within the coinnotch in theslide. When a coin is introduced into the. slot and' slide as appears in Fig.r 12,*'and as shown advanced under the dog in vF ig. 13, the dog is raised so that it rides-out thro-ugh the notch 124 permitting the slide yto advance and deliver `a ball of gum into the merchandise chute.

Thev ejector spring 18, seen particularly in Figs. `12 and 13,'comes into actionwhen the coin has passedfto position Vover the coin l passage to thecoin receptacle beneath, that operationwhen in use.`

osition being indicatedv particularly in *ig.`. 5. The 'spring'.18 has a downwardly bent elbovv181 which drops into the coin --notch and displaces the 'coin when the slide is moved to that position. The spring 18 has acoil on the pivot 161 of the dogand its opposite end 182 reacts against the top of `the dog house casing. The-free end 183 of this ejector sprmg reciprocates through aperture 152 in the top of the dog housing and kis guided thereby.

Thepan-like bottom platev rests upon a screw7 nut 63 ands a support for the remaining internalr parts. A nut 64 is pinned tothe shaft 6 and forms the opposite member ofithe clamp..,An intermediate nut 65 retains the'slide Vcasing members in position to serve as a journal for the slide and retain itin Placa Having now described the various parts .of my'structurmfvwill now indicate` their j A coin is introduced yat the chute or slot 142 as indicated bydotted linesin Fig. 4 and full lines in Figs'll, 12 and 13. It enters the notch 123 in the coin controlled mer- `derthe end of the coin controlled dog l16,v

elevates the same, so that the notchedpart 124 of the slidepasses underneath the dog y and permits the merchandise slide to act and carry a ball of gum Ato the delivery chute.' A ballot'. gumwhaving dropped intov the Vaperture 122, due to the-agitation of the balls by the lugs When it reaches the delivery point `it xdrops intothemerchandise deliverylchute, being retained therein by the gate 126. The control pawl 13 has then passed over the projecting teeth 145 when the slide has completed its stroke and the sam-e may be returned. Vhen the handle is E' released the slide `is retracted by the spring 17 and the merchandise, the ball or" gum, drops out through thek delivery chute to spout 11. It is not pos-sible to move the slide part waybeoause of the control dog 13 and it is not possible to partially Withdraw thesame and actuate it because the control dog 13 automatically engages to prevent that. Provision is made to prevent operation byr a slug or Washer slightly smaller P' than a penny by perforation 148.

itoo small a coin has been introduced, it is dropped down through the aperture 148 provided in the case 14 for that purpose. If a Washer has been introduced, as

`the point of the dog` Will be elevated from the center of the ivasherand both the washer and the coin will be delivered on the next stroke. This action will be understood by inspecting Figs. 12, lvand 14. The action of the dog in its operation is clear. lt has 1' dropped through a Washer, in Fig. 14, which `prevents the operation of the merchandise slide, and when a coin is disposed on top of this Washer, which is the position the coin Vwill take if introduced after the Washer, the

dog will be supported and pass both the VVcoin and the Washer.,` and thus operate 'fully and clear the machine. The depth oft' the recess for the coin is s uch that it will accommodate both the thickness of the Washer and the coin, such depth inno Way interfering with the operation of the machine on a single coin. When the mechandise slide has beenactuated Vto the limit of its stroke, the ejector spring 18 flips thecoin down through the aperturcinto the coin passage to the coin receptacle. This prevents tampering with the Amachine by attaching a ivire or a thread to a coin and introducing the same Y and withdrawing it on the return of the slide. It is till possible,`of course, to operate the machine by the introduction of a disk of the size of the Coin required, but as this machine is intended for a penny in the slot gum machine, it ishardly worth anyones While to prepare they necessary disks, the only danger being from the use of lWashers which are an article Which can be purchased in the marke)L at tritiing cost.

Having thus described my invention, What .V- iii) I claim as new and desire to secure byLetters Patent, is:
